Referring to the drawings in detail 1 generally indicates the pumpcylinder comprising a body Vportion 2 of any .suitable diameterfandwhich is open atits lower end and formed with a top 3 vprovided with va.centrally arranged opening L1. The top 3 Vhas an' integralupstandinginteriorly. thread@- ed collar 5 which forms a continuation of vtheopening. 4. Atubular 'member isfsecuredv vat its lower end to the collar5 and said-member 6' at its lower end' is formed with interior andexteriorthreads. The eX- terior .threads engage f. with the threads onthe inner face of the collar 5 and threadedly engaging with the interiorthreads` of the member y6 is an annular packing element 7. Thebodyportion 2 is anchored `withina wellv 8 or position'edvto communicatewith a source yof water supply. 'As shown the bodyportion 2 is ranchoredin the well'S and the tubular member 6 extendsfrom .the top 8 offfthebodyfportion 2 to the upper endof said well 8 and said member' issecured to a platform 9 which acts as a closure for the uppergendof thewell 8. The platform 9 isformedwithan openinglO for a purpose to behereinafter referredto. The vvmember 6 carries atop.pie'ce11 which abutsagainst the lower face of the V.platform 9 and is securedy to the latteror said `capy piece can be an integral partfof the platform 9 and se#cured to the member 6. -The platform, 9 has securedto its upper face a`packing elementl 12, and which forms a continuation of the opening 10in the platform 9. The platform 9 is lixedly secured in position bythehold fast devices 13. y

VConnected-to the platform 9 is aI pair yof spaced. vertically disposed,opposed standards 144, and the formerhas a bifurcated upper end terminalportion 16 and the latter a bifurcated upper. end terminal. portionl 17.Positioned yat the lupper ends offthe standards 14,. 15, is afsupporting` frame formed of a pair ofside membersj18,l19 and an. endmember20; Oneend ofthe frame isopen yand the other closed by the endmem-V 1,624,702-,v Erica.

ber 20. The open end of the frame is po-vv sitioned at the upperl endofthe standardv 15 and. the frame *projects` a substantial distancelaterally yfrom the: upper end ofthe standard 14. vThe side-members, 18andn'19 i oppose the upper `ends of the standard 14, .15, see Figure V2y4and the end Amember 2Oy is positioned a substantialdistance from `rthestandard .14. The side member-18 is formed with openings 21,22 and 23and the side member 19 with openings 24, 25 and The openings 23 and 26.aline and are arranged in proximity tothe open end rvof the frame;Theopemngs 21 and 24 aline andiare ar` ranged in proximity to the endmember 2OV of the frame. Theside member 181s formed v with airoffsetportion 2projecting laterally therefrom andthe side -member 1 9 with an'odset portion 28" which` projects laterally therefrom. lThe offsetportions27 and 28 are oppositely disposed with respect` to each otheryand `semi-circular yin contour. v The openings 22 and 254aline and arearranged betweenthe openings 21, 24andjthe offset portions 27, 28. Theinner face 'of the'side member 1S, between the openings 21and 22,

y is formedwith a vertically ldisposed l'ug'29 and the innerface 'ofthesidefmember 19 vbe;v .tween the openings`241 and 25 isprovided'with'J an inwardly.' extending klug `30. lThe lugs 29 and; 30 opposeeach other but are arranged in spaced relation. i Extending through thealining openings 21 and 24 is a shaft 31 for an idler roller 32 which ispo; sitioned between the side members 18 and 19. The shaft 31 -at oneend is provided witha head 33 and at its other end with a-collar 34which is detachably connected therewith. rllhe head 33 abuts against theside member a' 18 and the collar `34`against the sidemember 19. ThesideA member 19 hasits outer face provided .withy a pair of spacedapertured bosses 35., 36 and the former'ferms a contin-- uation of theopening and the latterthe opening 26. Extending through the aliningopenings 22, 25 and boss 35 is a .shaft 37 :tor a gear wheel 38 of thedesired diameter. The shaft 37 extends through the bifurcated upper endterminal 16 of the standard y14. One end of the shaft 37 carries a head39 which abuts the side member 18, and the other end carries a.removable collar 40 which abuts against the boss 35. Extending throughthe alining openings 23 and V2 6 is a shaft 41 upon which is mounted atoothed quadrant 42.

Extended romthe quadrant 42' aswell as being integral therewith is alever arxm 43. The shaft 41 extends through the upper end terminalportion of the standard '15 and also through the boss 36 and has one endprovided with a head 44 which abuts against the side member 18. Theshaft 41 has 'its other end provided with a removable collar 45 whichabuts against the boss 36. The uncf tion of the idler roller 32, gear 38and quadrant 42 will be presently referred to. l

Extending down through the platform 9, tubular member 6, and into thebody portion 2 of the pump cylinder yis arvertically inovable plungerelement consisting of, a tubular stem or rodI 46 and a' 'plunger headreferred to generally by the reference ycharacter 47. 4The vplunger orro'd provides means iior condncting'off the water fromv the well 8during the operation et the plunger element. y end is provided with anenlargement l48 formed therein with a: beveled valve seat 49 for a checkvalve 50. The enlargement 48 is provided with peripheral threads. Seatedon the edge of the enlargement 4 8 is a perforated disk 51 whichconstitutes a retaining member vfor the check, valve 50. The disk 51 isfixedly secured against the upper edge of the enlargement; 48 by acoupling'niember 52 which threadably engages with the peripheralthreads' of the venlargement 48. The coupling member 52 overlaps thedisk 51,` see Figure 1, and has itsvupper end formed with interiorthreads' for securin'gtheiew-ith an upstanding goose neck 53..` The.diameter oi' the plunger rod 46 is less than that of the inner`diameter of the tubular member 6 and said rod 46gextendsthrough-thepalcking element 12-and also throughthe packing The plungerrod 46 at its upperr element 7. The lower end of the rod 46 is `portionformed of an upper section 55 and a lower section 56. The sections 55and 56 are connectedy together as at 57. rllhe section 56extends intothe lower portion of the section55, and threadably engages with thelatter. The section 56 central-ly thereof is formed with an inletopening 58 and with an upstanding collar 59 having a lbeveled top edgeyand which forms a continuation of the opening 58 and.` further providesa seat for a. v'valve 60 which is pivotally,connected as at 61, to anupstanding lug 62'0n the 'upper face of the section '56. The section55has its ktop formed with a circular row of openings 63 and a centrallydisposed opening 65. The lower -tace of the top ot the section 55 isprovided with an interiorly threaded collar 66 which is spaced anappropriate distance above the collar 59. The valve60 operates betweenthe collars 59 and 66 and its upward movement is arrested by the collar66. When the valve 60 is mounted on the collar 59 the plunger head 47 isclosed. Gr in other words when the valve 60 is mounted on the collar 59the inlet opening 58 is closed. The collar 66 threadably engages withthe threads 54 at the lower end of the plunger rod 46 for the purpose ofconnecting the plunger head 47 to the lower end of the rod 46. The lowerterminus of the rod 46 is spaced an appropriate distance above the inletopening 58, see Figure 1. Surrounding the plunger head 47 is apackingmember 67 which rides against the inner face of the body portion2 of the pump cylinder see Figure 1. The plunger head 47 is flanged asat 68, 69 for the purpose of retaining the member 67 in position. i

Clamped against the plunger rod 46, an appropriate distance above theplatform 9, is a pair of rack members 70, 71. The rack members 7 0,71are oppositely disposed with respect to each other and the member 70 isformed with a lengthwise ext-ending toothed rack 72l and the member 71with a' length wise extending toothed rack 73. Each of said rack membersis semi-circular incontour and provided with a pair of-oppositelyextending flanges v74. The flanges of one rack member abut againsttheflanges of the other rack member and are secured 'together by the'holdfast devices 75. The rack 72 associates with the gear wheel 38 and therack 73 associates with the quadrant 42.

Interposed between the idler roller 32 and 'the gear 38 is a verticallyshiftable counterbalancing element consisting of a vertical bar 76provided in its lower end with a weight 77. O ne side edge of the bar 76is toothed as indicated at 78 and which asso- Y tlie water which isconducted off through tlie plunger rod 46 and such equalizationovercomes excessive leverage under-such conditions permitting theoperation of the pump oi' device with the least possible expenditure ofpower.

When the plunger element is in its lowered position within the pumpcylinder, the valve 60 will permit of water entering the plunger headandfrom there passing into tlie body portion 2 of the pump cylinder. Ontheupward vmovement of the plungerelement the weight of tlie waterwithin the body portion 2 will close the valve 60 and as the plungerHmeans in a contra-direct direction with respect to the reciprocationyof saidelement,

head moves upwardly the water will be forced into the plunger rod 46 anddischarged therefrom through the goose neck 53. W lien the plungerelement moves downwardly, the counterbalancing element moves upwardlyand when the plunger element movesl upwardly the counterbalancingelement moves downwardly, and by this arrangement a counterbalancingmeans is provided on the downward and upward movement of the plungerelement.

In lieu of employing the counterbalancing element, `a pair of pumpdevices can be arranged side by side in a mannerwhereby the gear wheel38 will be common to tli-e two piston elements and by this arrangementone of the pumps or devices will act as a counter-balancing means forthe other.

The plunger element is vertically shifted 1. on the swinging of. thequadrant 42 by tlie lever 43. l/Vhen the lever is swung upwardly theengagement of the quadrant with the rack 73 will move the plungerelement downwardly providing what may be termed a water intake stroke,and when the lever 43` is swung downwardly, the quadrant 42 inconnection with the rack 73 will move the plunger element upwardlyproviding what Y may be termed a water elevating and dis-` chargingstroke. The quadrant 42, rack 73 and lever 43 provides means forreciprocatv ing the plunger element.

It is .thought ythe many advantages ofv 'a p pump vor water liftingdevice, in accordance with this invention, can be readily understood,and although the 'preferred embodiment of the invention is asillustrated and described, yet it is to be noted thatchanges in thedetails of construction can vbe had which will fall within the scope ofthe-invention as claimed.
